PAM8906M1012-13

Overview

The PAM8906M1012-13 is a piezoelectric sounder driver manufactured by Diodes Incorporated, designed for battery-operated alarm and haptic feedback applications. It integrates a boost converter capable of generating a 12V output from a 2.1V to 5.5V supply, driving piezo sounders up to 36Vpp. The device supports external PWM input or self-excitation modes (for 10V/12V versions) and features low quiescent current with automatic shutdown control. Packaged in an MSOP-10 format, it includes thermal shutdown, overcurrent protection, and undervoltage lockout.

Feature Summary

• Integrated boost converter providing 12V output with 36Vpp capability
• Supports external PWM input and self-excitation mode
• Low operating current with shutdown current less than 1μA
• Automated wake-up and shutdown control via DIN pin

Applications

• Smoke, gas, and water alarms
• Industrial security devices
• Air humidifiers and ultrasonic drivers
• Haptic feedback systems

Procurement Notes

Verify the specific voltage option suffix (12V for M1012) against system requirements. Confirm AEC-Q100 automotive qualification status if required for the application. Ensure packaging matches the 13-inch tape and reel specification indicated by the -13 suffix.

Selection Notes

Select this component when a compact MSOP-10 package is preferred over larger footprints. Choose the 12V version specifically for three-terminal piezo sounders requiring that intermediate voltage level. Ensure the input signal frequency falls within the 0.2kHz to 10kHz range for standard operation.

Part Context

This part belongs to the PAM8906 series, which offers 10V, 12V, and 18V boost output options. The M1012 designation specifically identifies the 12V variant housed in the MSOP-10 package. It serves as a direct replacement for previous generation drivers requiring higher SPL with lower power consumption.

Replacement Considerations

PAM8906M1010-13 (10V Output) and PAM8906M1018-13 (18V Output) are functionally similar variants within the same package family. Verify that the target piezo sounder impedance and voltage rating align with the 12V boost output before substituting.
